Ask a question

Take 10 golden ratio triangles (called a 'gnomon' like the tool used a few days ago) where one long side is bigger than the other two sides by the golden ratio (1.618 approx). The reason for taking 10 is that the smaller angles of a gnomon is 36 degrees, or 1/10 of a circle. Bring all the points together and then rotate one triangle by 36 degrees, the next by 36+36 and so on. You've created a windmill.

Now create 6 copies of the windmill, each 61.81% the size of the last (that golden ratio again, but this time its inverse). Place them on top of the original windmill and then rotate them in the same way you did the original triangles. Add colour to taste.

Once again, because so much is governed by the golden ratio, there are unexpected alignments everywhere if you draw horizontal or vertical lines through significant points. The most important relationship, which makes the whole thing work, is that the long side of each triangle in one fan is the same length as the short side of the triangles in the next largest.

In the third photo you can see the first three stages, which may be clearer than an explanation using words! Note that the third photo is not included in your purchase, it is there for explanation purposes only.

Additional

The colours you are seeing on your monitor are inevitably not precisely the colours you would see if you were looking at the same design in printed form. There is simply no way around that, since the internet places limits on the range of colours that can be displayed and, even if that were not the case, every monitor is subtly (sometimes wildly!) different in the way it displays colours.

But you can be reassured that the quality of our equipment is such that colours and quality are consistent over time and the print you receive will be identical to other prints sold in galleries and art fairs to buyers who have every opportunity to handle and assess them.
